Abstract: Various embodiments disclosed herein provide for switching between non-orthogonal and orthogonal multiple access protocols dynamically. A base station device can determine whether a user equipment device on a communication link should use a non-orthogonal multiple access system or an orthogonal multiple access system based on one or more attributes of the communication link, and send an indication of the selection to the user equipment device. The base station device can indicate the selection using a spreading factor parameter that is either equal to one or greater than one. If the spreading factor parameter is equal to one, that can indicate to the user equipment device to use an orthogonal multiple access system, whereas if the spreading factor parameter is greater than one, that can indicate to the user equipment device to use a non-orthogonal multiple access system.

Abstract: The described technology is generally directed towards indicating to a receiver (e.g., a user equipment) which antenna ports are assigned for channel state information reference signals (CSI-RS). The indicator can be sent as radio resource control configuration data and/or by physical layer signaling such as in downlink control information. The receiver computes CSI based on the assigned antenna port or ports, and the reported (e.g., joint) CSI helps avoid mismatched joint CSI used for scheduling when multiple transmit and receive points (TRPs) are communicating with the user equipment.

Abstract: The gains with non-orthogonal multiple access (NOMA) for uplink data transmissions can be high when chosen codes are orthogonal. However, when codes are non-orthogonal, the gains can be low. NOMA can be used when there is more than one mobile device using the same resources. Since orthogonal codes cannot be possible for every length, codes which have low cross-correlation properties can be used. However, when there are a large number of mobile devices using the same resources, the cross-correlation between the codes can cause interference to the mobile devices. Reducing the gains of a NOMA system can reduce the overall throughput. Thus, transmitting data on the same resources in a NOMA can occur in spite of the interference to the UEs transmitting data on the same resources. Therefore, a non-orthogonal multiple access design for a 5G network can mitigate interference.

Abstract: Aspects of the subject disclosure may include, for example, obtaining a received channel-encoded data block having information bits, a transmitted error-check value, and redundant code bits.

A channel code type is identified and responsive to it being systematic, the information bits and the transmitted error-check value are obtained without decoding according to the channel code. The received channel-encoded data block is checked according to the transmitted error-check value to obtain a result. Responsive to the result not indicating an error, extracting the information bits without decoding the received channel-encoded data block according to the channel code. Responsive to the result indicating an error, decoding the received channel-encoded data block according to the channel code to obtain decoded information bits. Other embodiments are disclosed.

Abstract: The described technology is generally directed towards dynamically changing which quadrature amplitude modulation (QAM) table a user equipment is to use based on channel quality information. A network schedules a user equipment with 256 QAM modulation if the user equipment recommends 256 QAM in the CQI report (and the scheduler decides to use 256 QAM for that particular user equipment). The network indicates to the user equipment that it has to use 256 QAM modulation and coding scheme (MCS) table and not the configured QAM MCS table while determining the scheduling parameters by decoding PDCCH.
